Hi there!

Thanks for your query. There is no default way to do that. It requires copying add-on FILES and related CSS & JS code.

In theory, coping add-on from template A to template B is possible. Location: templates\shaper_TemplateName\sppagebuilder\addons

But you have to remember that in some cases, addons have unique CSS and js which was included inside the template.css and template.js file of the template.

So you have to Copy those as well.

The following video tutorial may help you:
